Network issue above 2.5.1.1
Hi,
WHen running a QEMU guest (Windows7) on a linux x86-64 server, the network stops working after some time for any version above 2.5.1.1
In 2.5.1.1, all is fine (no issue with network)
Any version ablve (trying 2.10.1 now), the application in windows stops accessing the internet after a while
THis is my starting line:
/usr/bin/qemu-system-x86_64 -machine pc-i440fx-1.7,accel=kvm -usb -usbdevice tablet -usbdevice keyboard -enable-kvm -cpu core2duo -smp 2 -drive file=winpro.qcow,index=0,media=disk,format=qco
w2 -m 4096 -vga vmware -vnc :3 -k en-us -device e1000,netdev=nic1 -netdev user,id=nic1,smb=/data/vps/files/,hostfwd=tcp::10053-:10053,hostfwd=tcp::3387-:3389 -rtc base=utc,clock=host -daemon
ize
Thisis my configure line:
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --enable-kvm --disable-gtk --disable-xen --disable-user --enable-vnc-sasl --disable-libusb --disable-debug-info --disable-spi
ce --enable-lzo --enable-pie --disable-werror --enable-linux-aio --enable-vhost-net --disable-tcmalloc --enable-vde --enable-nettle --disable-smartcard --enable-curl

Does tcpdump on the host show outgoing connections to an external IP
address (not a domain name)? For example, try opening to
http://172.99.69.163/ from inside the guest and check that there is a
TCP SYN packet sent from the host to 172.99.69.163.
Do the hostfwd ports still work while internet access is down?
